Network & Infrastructure
Network infrastructure design, installation and support
Design, deployment and support for reliable business network infrastructure.
A reliable network underpins every application, device and employee. SGM provides network consulting, network installation and ongoing support for business environments — from switching, firewalls and Wi-Fi to structured cabling and fiber.
We work with Cisco, Fortinet and Meraki environments and recommend equipment around your requirements and budget. The most expensive option is not automatically the right one. We also consider the ongoing cost of unreliable equipment, missing backups or neglected updates.
